Layered and 2D materials are currently one of the most well-studied classes of solid-state compounds, due to the plethora of unique physical phenomena found in these anisotropic materials. Here we will describe our recent work in the synthesis, properties, and applications of layered materials that exhibit either n-type or p-type conduction behavior depending on the crystallographic direction, a phenomenon we refer to as “goniopolarity”.   We will establish the origin of this exotic behavior and the band structure design principles for identifying new goniopolar materials. This understanding has led us to rapidly expand the number of materials that exhibit this behavior. Finally, considering that most modern electronic devices require the integration of p-type and n-type regions for functionality, we will show how the unique charge separation in goniopolar materials have the potential to create new architectures of highly efficient energy-harvesting and electronics technologies.

Speaker Information

Josh Goldberger received his B.S. in Chemistry from The Ohio State University in 2001. He received his Ph.D. in chemistry from the University of California at Berkeley with Professor Peidong Yang in 2006, as an NSF graduate fellow. He then did his postdoctoral research with Professor Sam Stupp at Northwestern University as part of the Institute for BioNanotechnology in Medicine, as an NIH-NRSA postdoctoral fellow (2007-2010).  He has received many awards, including an MRS Graduate Student Finalist Award in 2003, an IUPAC Prize for Young Chemists in 2007, a Camille Dreyfus Teacher-Scholar Award in 2015, a Lumley Interdisciplinary Research Award in 2019, and an ASC Mid-Career Excellence Award in 2020.  He was elected to the AAAS in 2022, and received a Friedrich Wilhelm Bessel Award from the Humboldt foundation in 2022.  In 2023, he became the director of the Center for Emergent Materials, an NSF MRSEC center. He joined The Ohio State University Chemistry and Biochemistry Department in August of 2010, and was promoted to Associate Professor in 2016, Professor in 2020, and is currently the Charles H. Kimberly Professor.  He is a co-founder of Goniotech LLC and has a joint appointment with the Department of Materials Science and Engineering.
